<h2>Message</h2>
<div class="docbody">
<p>Unregistered <code>link</code> relationship: <code>foo</code></p>
</div>
<h2>Explanation</h2>

<div class="docbody">
<p>The current values for the <a href="http://www.iana.org/assignments/link-relations.html">Registry of Atom Link Relations</a> are as follows:</p>
<ul>
<li><code>alternate</code></li>
<li><code>current</code></li>
<li><code>enclosure</code></li>
<li><code>edit</code></li>
<li><code>edit-media</code></li>
<li><code>first</code></li>
<li><code>last</code></li>
<li><code>license</code></li>
<li><code>next</code></li>
<li><code>next-archive</code></li>
<li><code>payment</code></li>
<li><code>prev-archive</code></li>
<li><code>previous</code></li>
<li><code>related</code></li>
<li><code>replies</code></li>
<li><code>self</code></li>
<li><code>service</code></li>
<li><code>up</code></li>
<li><code>via</code></li>
</ul>
</div>
<h2>Solution</h2>
<div class="docbody">
<p>Change the attribute value to one in the list.</p>
<p>If a value other than one of the above is desired, either register
the relation with the IANA registry, or express the rel as a fully
qualified URI.</p>
